Benefits of technology
[0007]In one embodiment, the automated needle deployment device comprises a pusher, a needle, a tube, and an actuator. The pusher has a needle engaging end. The needle has a sharp end and an opposite end. A suture is associated with the needle. The pusher and needle are slidably disposed within
Problems solved by technology
Certain prior closure devices have involved relatively complicated methods and devices for extracting a length of suture from inside the vessel so that the physician can approximate tissue surrounding the hole in the vessel wall through use of the suture.
Most prior closure devices enlarge the vessel opening thereby negating the benefits of using smaller or less invasive percutaneous products.
Prior suturing devices are also relatively complicated and difficult to use.

Embodiment Construction
[0022]A device for automated needle deployment and a method of using such device is disclosed. Medical systems and devices for suturing internal tissue walls included such automated needle deployment device are further disclosed. More particularly, an automated needle deployment device suitable for use with an internal tissue suture delivery system for performing medical procedures that include delivering needles and sutures to internal tissue for closing internal tissue walls after an opening or puncture in tissue has been made is provided. The automated needle deployment device may form a part of a needle and suture delivery unit. Tissue that may be closed in accordance with the teachings herein may be part of a lumen such as a blood vessel, body cavity, other organ, or any tissue suitable for suturing. In one example, vascular suture delivery systems such as disclosed in copending U.S. patent application Ser. No. 11 / 551,523, filed Oct. 20, 2006, may be used to deliver needles and...

An automated needle deployment device is provided. In one embodiment, the automated needle deployment device comprises a pusher, a needle, a tube, and an actuator. The pusher has a needle engaging end. The needle has a sharp end and an opposite end. A suture is associated with the needle. The pusher and needle are slidably disposed within the tube. The actuator comprises a control and a spring and is operatively associated with the pusher. Actuation of the actuator moves the pusher towards the needle expulsion end of the tube such that the needle engaging end of the pusher engages the needle and expels the needle from the tube.
Description
FIELD OF THE INVENTION[0001]The present invention generally relates to medical systems and devices for suturing internal tissue walls, and more particularly to a device for automated needle deployment and to a method of using such device.BACKGROUND OF THE INVENTION[0002]Various medical procedures, particularly cardiology procedures, involve accessing a corporeal vessel through the formation of a hole or opening in the vessel wall so that a medical procedure can be performed. After the particular medical procedure has been performed, the access hole in the vessel wall must be closed.[0003]A number of prior vascular closure devices and methods have been developed in attempt to provide a solution for the problem of closing a hole in the vessel wall. Tissue approximation typically involves passing a length of suture into and through adjacent vessel and subcutaneous tissue, across the vessel opening, and back into and through adjacent vessel and subcutaneous tissue. Certain prior closure...
